Abstract: Implementations generally relate to communication between a lens assembly and a camera. In some implementations, a method includes establishing electronic communication between a lens assembly and a camera, wherein the lens assembly is removably attached to the camera. The method further includes exchanging capability information between the lens assembly and the camera, wherein the capability information includes one or more functional features. The method further includes matching one or more of the functional features that both the lens assembly has and that the camera has. The method further includes enabling the lens assembly and the camera to cooperate in providing functional features based at least in part on the matching of one or more of the functional features.

Abstract: Implementations generally provide physically based camera motion compensation. In some implementations, a method includes detecting vibrations at an image sensor of a camera. The method further includes determining a vibration signal from the vibrations, wherein the vibration signal includes one or more of a horizontal component and a vertical component. The method further includes sending the vibration signal to one or more actuators, wherein the actuators dampen the vibrations.

Abstract: Implementations generally increase the virtual resolution of a camera sensor. In some implementations, a method includes moving an image sensor in a predetermined pattern, wherein the image sensor includes an array of light collecting elements, and wherein each light collecting element of the sensor array cycles through a plurality of positions in the predetermined pattern. The method further includes capturing a plurality of samples of light at each light collecting element, wherein each light collecting element captures a plurality of the samples in a cycle of movement in the predetermined pattern. The method further includes converting each sample captured at each position into a value. The method further includes generating at least one image from an aggregate of values converted from the samples of light.

Abstract: A customer can install a lenticular projection screen without the need to hire a professional installer. A section of a home wall is smoothed flat and lenticular tiles are applied to it with adhesive together establishing a lenticular projection screen. Once the adhesive has dried, a short throw projector can perform an automatic alignment to gain the best possible picture from the lenticular screen. The installation material may be provided as a kit that a consumer can use to install the lenticular projection screen.

Abstract: An overlay panel that includes a front display portion arranged over surface area of a display device. The overlay panel further includes a guiding portion that comprises light guides arranged in a specific pattern. The light guides are arranged such that an input portion of each light guide is aligned with pixels or sub-pixels of the display device and an output portion of each light guide is coupled to the front display portion. The arrangement of each light guide transfers an excitation, caused by the set of pixels or sub-pixels, from the input portion to the output portion and causes the front display portion to display an image that covers a bezel portion and the display portion of the display device. Each pixel in the image is scaled by an equal scaling factor with respect to each pixel in display portion.

Abstract: A glass (or other transparent) substrate such as a window is used for large screen video projection to permit viewing at an outdoor location (or opposite side of the substrate) of a video projector's image directed from a location in the home. The projector image is sent through an articulated glass window pane (substrate). Alternately a projector such as an ultra short throw (UST) projector can be completely located behind the transparent glass pane located in a home separating two rooms. In either case, the video image can be projected onto the substrate when desired, and when no video is being shown the substrate functions as a window or displays window art as a wall covering.

Abstract: To avoid requiring precise alignment between a projector and a projection screen, plural micro etched faceted grooves are provided for each area of the screen onto which a single pixel is to be projected. Each facet may be roughened, or gently curved, and the walls between adjoining facets likewise may be curved.

Abstract: A multichromic reflective coating is applied to a projector screen to reflect only those wavelengths produced by the projector, to accentuate selective wavelengths of light to be reflected. The screen can be a passive black substrate or an active grayscale screen such as e-ink paper, and un-reflected light reaches the screen which selectively tunes its grayscale to accentuate the brightness or darkness of the color video image being projected onto it and reflected by the multichromic reflective coating.

Abstract: Meta-material with individually-addressable elements is applied to a video projector screen to dynamically control light reflectance and grayscale. Example meta-material includes piezo electric elements, liquid crystal elements, and electrochromic elements. Methods of calibrating the screen with meta-material are disclosed. In one embodiment the screen is adjustable pixel by pixel. In another embodiment the screen is adjust by multi-pixel spans per line of meta-material. A camera may be used to provide feedback to the alignment system to make corrective adjustments to the screen.

Abstract: A dual layer e-screen includes a top layer of a transparent lenticular or parallax material backed by an e-screen made of a material with controllable grey scales such as electronic paper. The top layer is controllable compensates for ambient lighting by creating a controllable surface that allows for uniform light distribution across the screen, while providing for adaptive contrast levels that selectively darken areas where light is not needed to more accurate display shadows from projected images. The eScreen can be additionally arranged to dynamically alter the gray scale matched to the video being shown to support viewing high dynamic range video through a projector. The gray scale used for each pixel element is biased to the ambient lighting conditions to remove the ambient light from the HDR video playback.

Abstract: A deformable lens, deformable micro-mirror array, or combination thereof adjusts an image projected onto a screen to modify that image to compensate for small imperfections in the flatness of the surface the video is being projected onto. Initial calibration can be performed to create a screen profile, that is then used to adjust the optics to compensate for the detected screen anomalies. An initial grid projected onto the screen may be used for this purpose, with a high resolution camera imaging the grid and the perpendicularity, straightness and sharpness of the grid lines then being assessed by a processor to calculate the necessary optical modifications to modify the projected image such that the grid lines are straightened and aligned. In another embodiment a scanning laser is used to assess screen flatness and uniformity with pixel level precision.
